Application filed September 24, 1924. I Serial 1101739303.

, object is to provide simple measuring de-' vices for operation with bins or hoppers which contain material so that uniform amounts 1 of ingredients amounts 'of mixed material may be secured and to provide means for varying the capacity of the measuring devices asmay be re-' quired, that is, means for increasing or decreasing the amount of material as. maybe required. The handling o f sand; stone or pebbles, or cement has been largely accomplished by transporting such materials from the supply sources in Wheel barrows or trucks which are'loaded by workmen using shovels. Such handling is not uniform for many reasons. My device as proposed for protection against carelessness and 'fraud in such workhas been demonstrated to be absolutely accurate and invaluable to to the end that correct proportions and amounts of material are insured in such manner thatit would'be impossible for a different amount of-material to be obtained in any volume'of different batches so measured. The same measuring device may be used when the mixed concrete is to be transported from the mixer to a street or road where it is to be laid so that the thickness of the, concrete will be uniform. Other objects 7 and advantages will. be fully explained in the following description and the invention will be more particularly pointed out in the claims. I V I Reference is had totheaccompanying drawings Which form a part of this-application. I

A portable bin'or hopper is herein set forth, and it may be preferable to make a double. bin or hopper and drum because the two sets of double equipment can be more economically constructed together than it would be to build twoseparate structures.

A double hopper 18 is mounted *on the frame and provided with a divider 17. at

the central portion for directing material An upright frame is provided with supports or posts 1', 2, and 3 to which are attached "I 1 beams 5 and6; The framemay be com- I plete by cross-beams 4:,7,8,"and' 9, which to the measuring drums or receptacles 11 and i 12. The drums 11 and 12 are cylindrical structures with openings 15 in their upper sides to receiv'e'material from the hop'pers. The drums may be independently operated..

The drumll is provided with stub shafts 19,

which are rigid 7 therewith to, be jour'nale'd in the cross-beams -7 and "8 and the-drum 12 1s provldedwith stub shafts 20 whichareto be 1ournaled 1n the cross beams 8 and 9.

The drums 11 and 12 may be revolved by any suitable gearing. I p are rigidly mounted'on the shafts 19 and 20 and levers 22 are pivotally connectedto the The hoppers 18 have curved flanges 26L on their lower edgesto form sealing devices with portions 25 of the drums 11 and :12

which as shown are not cut away at the Each drum, 11 and 12, may be divided into two compartments, as shown in,Figs.'2 and 4. Two openingsfil5, one for each com artment, are'for'med for receiving and disc arging material. The drum 11 is divided by'a diametrical partition, making two compartments 11 and 11"." .There maybe different" I a is then bent'inwardly' toform the partition members 26'. and 27 which meet at the'lo ngitudinal center of the drum.- It is apparent that the members 26*27 and 26'-2 7'.may i cal capacity of the compartments 11 and 11,. Divider partitions 28 and 29 are mounted rigidly on disks 30 and 31 and the disks 30 and 31 are revolubly mounted onJthe stub shafts 1-9 and The divider partitions 28 tan-d2?) may be turned..,to any requircdr position within the compartments 11 and 11 to increase or decrease the cubical capacity A of thesecompartments,' The disk 31 hasan aperture 32 and the adjacent. drum head 28 has aplnrality of {apertures- 33. A pin 34 may be used to fix the disk ,31;in Whatever I pesitionzthat maybe required. -The di-sk3l [will be revolved to bring the aperture 32 to. the aperture 33 hich is required then r a pin 84 inserted into the head 28 and into the disk f to fixedly positionthe disk 31 to thehead and consequently fix the ."dividers-ZS and .29 in position'so that the compartments l1 and 11 will contain the 'rcquiredamount of material. I iYielding cut-,oflis 3,5 are attached to the i hoppers 1,8 to prevent surplus material from tollo ving the discharge openings 15. The f ielding gentolts mayconsist otsteel brushes. in order to prevent material from falling out et the drnm-s prcmatnrely, guards 36. are placedback of the d ninsiland curved downr ivarldlyflas shown.
